JET BOX. FOR BOTTLE-WASHING MACHINES. .i

Application sled February 1o, 1923. serial. No. crassa;

This invention relates to jet or spray boxes of the kind used in connection with bottle washing machines, particularly with` equal pressure from all of the discharge ori-' fices of the box; also to so construct the jetV box that the foreign matter in the liquid will not tend to obstruct thel flow of liquid through the orifices; also to provide the-box with removable parts or caps which are' formed to collect foreign matter from the liquid supplied to the jet boxes and which when removed permit ready access to the interior of the jet boxes; also Vto improve the construction-of jet boxes in other respects hereinafter specified.

In the accompanying drawings:

The jet box shown in the accompanying i drawings is intended to operate simultaneously on two crates or casescontaining either quart or pint bottles, but it will be understood that the invention may equally well be used inconnection withjet boxes which operate on only one crate at a time,` Oron one size of bottles.-

The jet box embodying the invention which is shown int-he drawingsincludes a hollow cast-ing having a central supply tube or passage A' which extends transversely of the jet box and is preferably provided at one end with a 'fia-nge or other means a for connecting the jet ,box with. asupply*A of,

yboxesmust be adapted to operate on either or crates containing a dozenbottles, and the liquid and at the other end with a removable plug. a. which 4facilitates the cleaning of this passage. The central passage A connectswith a plurality of spray tubes or passages B which vproject from opposite sides of the -central supply passage A and which are-spaced apart to provide apertures or spaces C through which the water running from the bottles may be discharged.y` The spray tubes are preferably arranged to receive liquid from the upper portion of the supply passage, so that foreign matter car-- ried into the jet box due to the recirculation of the washing fluid will not tend to close the discharge orifices in the spray pipes. The closed end of the supply passage is preferably provided with a depressed portion orwalla2 which serves to collect for- .eign matter from the fluid. The spray tubes are provided with substantially flat upper faces in whichl the 'discharge orifices are arranged. These'orifices are preferably' so positioned as to project jets of water or other fluid into the-bottles and since the jet pint or quart bottles, two .sets of discharge orifices are provided, a set of orifices b serving to projectjets of liquid into quartbottles, whichare` generally arranged in cases' orifices b serving to prdject liquid into 'smaller bottles, which` lare generally arranged in cases containing twenty bottles. The spray tubes B, owing to the lnecesslty for arranging the discharge orifices in donite positions on the jet boxes, may be made of different shapes in cross section, depend ing upon the location ofthe orifices, and

consequently the spaces C between the adja cent spray tubes also vary in shape, as 1s indicated clearly in Figs. 1 and VBy providing spaces or openings in the Jet box, the

vWater discharged from the bottles upon the flat upper face of the jet box will be quickly discharged or drained therefrom and thus offer very little resistance to the flow of liquid through the orifices. This arrange-A j ment, therefore, greatly increases the eii-` ciency of jet boxes of this type' 1n that very little of the force of the water is lost in kovercoming the resistance .of a layer of water on the jet boxes, and consequently the y f orce thus made available serves to more thoroughly cleanse the bottles.` The outer ends of the spray tubes B arel 30 the jet boxes.

45 are otherwise located so as to U be removed from the jet boxes,

5 connectin end members D are preferably Yopenat t e opposite ends of the jet boxes Iand are adapted to be closed by means of removable caps or end pieces E, which are referably arranged at an inclination.

hese caps are hollow and trough shapedin cross section and may be secured' to the ends of the jet boxes in any suitable or desired manner, for example, by means of machine screws or the like e passing through l5 the end pieces and engaging in threaded holes e in the connecting end members D. The trough shaped portions e2 of the caps or end members E, due to the inclined ary rangement of the end caps, extend below the spray tubes B and serve to collect forei n matter which may be introduced into t e jet boxes with the washing or `rinsing liquid.

It has been found that most of the foreign matter found in rinsing or washing water has a tendency to pass lengthwise of the spray tubes B to the ends thereof and to become depositedin the trough shaped portions of the caps, where it can be conveniently removed bv detaching the caps from he caps may, if desired, also be provided with plugs f which can be removed to permit the accumulation of `foreign matter 1n the trough shaped portionsin the caps E to be discharged from` the jet boxes without removing the caps therefrom.

When the caps. E are removed fromthe jet boxes, the interiors of all of the spray tubes B- are rendered readily accessible so that foreign matter may be removed therefrom 40 by means of thecleaning brush or other de vice. By arranging each end cap E at an inclination to the jet box, these end caps can be readilyy removed even if the jet boxesy are arranged close together in a machine or prevent .ready access to the ends of the box, and this inclined arrangement also facilitates the insertion of brushes or other cleaning devices when the end caps are removed and when the )et boxes are arranged in close proximity The depressed end a2 of the central supply passage ean be readily opened by means of the plug ai to permit foreign matter to and by arranging the end caps E at an inclination so that the trou h shaped portions thereof ex-l tend. below t e spray tubes B, it will be readily seen that the tendency of any foreign matter entering into these troughs wouldbe to remain in the troughs. The foreign matter is thus kept from the orifices p and as a result of the construction described the jet boxes are less apt to become clogged with foreign matter than similar devices heretofore made. The.trough shaped end caps E, however, also serve to equalize the pressures in the various spray tubes B so that all of the jets will be discharged from the boxes at substantially the same pressure.
